Abstract: A pivotal pistol grip firing mechanism mountable upon an operator-portable rocket launcher for use in aiming and electrically arming and firing a rocket loaded within the launcher is disclosed. A mounting bracket attached to the exterior of the launcher supports a pistol grip pivotally, between a carrying position and a firing position. The pistol grip houses a percussion activated thermal battery together with a firing pin assembly for activating the battery to supply power to fire the rocket. Energy to activate the thermal battery is not available until a firing pin spring is compressed by positioning the pistol grip in the firing position. A trigger and safety lever assembly in the pistol grip control the release of the firing pin. A manual safety switch in the pistol grip circuitry prevents transmission of the battery output unless closed by the operator prior to firing.

Abstract: A matrix multiplier system incorporating an integrated fiber optic coupling array in combination with an arrangement for individually modulating the signals on the respective optical fiber transmission lines to develop the matrix multiplication. Each of the individual couplers accomplishes the coupling of an input signal into a bi-directional fiber optic transmission line with high efficiency and unilateral coupling effect. The signal thus coupled into the bi-directional transmission line is reflected back to the coupler output after multiplication by the modulating vector component for the individual coupler element. Because of the fabrication of a large number of identical fiber optic couplers in a compact, integral array and the manner in which the light signals can be modulated, the matrix multiplier system is extremely effective in pattern recognition, signal discrimination, selected signal enhancement, and the like.

Abstract: An optical image scanner utilizing an integral array of fiber optic launch couplers to direct an input light image to a selectively reflective termination and then to an output termination. The selectively reflective termination is sequenced to scan the bidirectional fibers of the launch coupler array to direct, in turn, the light transmitted through the launch coupler to the output. Thus, an input light image, applied in parallel, is scanned to develop a serial output for the respective pixels of the image. In one particular arrangement in accordance with the invention, the selectively reflective termination comprises an array of binary driven Faraday rotators. In an alternative arrangement, the reflective scanner comprises a rotating disc with a single reflective spot positioned near the periphery and facing the terminal ends of the bidirectional fibers of the launch coupler array.

Abstract: Constituent pyrotechnic materials are dispensed by prescribed weight or volume into a single container containing an excess volume of an inert liquid, such as Freon T.E., having the property of preventing ionization of the materials. The pyrotechnic materials in inert fluid medium are then stirred so as to obtain an homogeneous slurry mixture. The slurry is allowed to settle and the inert fluid is decanted off for future reuse. The remaining slurry is dispensed into individual containers under pressure. The slurry is vacuum dried at a safe temperature to minimize the accidental ignition hazard while removing the remaining inert liquid, thus forming individual casts of pyrotechnic material. The casts are permitted to reach ambient temperature and pressure at predetermined rates so as to prevent cracking of the pyrotechnic charges.

The pressure pulse of the shock wave removes the end caps fitted over the open ends of the cannister.

Abstract: A method for augmenting a noise-adaptive predictive proportional navigation terminal guidance scheme. In a second order configuration with noise adaptive varying gain parameters calculated as a function of time-to-go, this system implements an optimal control law to augment proportional navigation with a missile acceleration feedback term and a navigation ratio to account for first order autopilot time lag. This configuration results in nearly optimal miss distance behavior, with sensitivity to unmodeled errors being substantially less than that in modern guidance systems. The system is particularly useful for high altitude, minimally maneuvering targets.

The techniques employed and the resulting devices permit coupling between pairs of individual fibers joined in the manner described.

Abstract: A projectile body has a gyro mounted therein including a rotor and a mechanism for supporting the rotor for rotation about a spin axis initially coincident with the longitudinal axis of the projectile body and pivotable away from the longitudinal axis of the projectile body. The rotor is initially locked to the projectile body so that it is spun with the projectile body during launch. Thereafter, the rotor is unlocked and the projectile body is de-spun to a relatively slow rate of rotation while transferring angular momentum to the free spinning rotor which continues to rotate at a high rate relative to the projectile body. Rotationally phased steering commands, which are generated from on-board homing sensor signals or up-link data signals received from a remote error sensor, are applied to a linear actuator within the projectile body. The actuator pivots the spin axis of the rotor away from the longitudinal axis of the projectile body.
